SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal Extension-II) in Predicting Mortality and Morbidity in NICU

Abstract

Introduction: A number of illness severity scores have evolved which would predict mortality and morbidity in intensive care units. One such scoring system developed by Richardson was SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal extension-II). Aim: The present study was conducted to assess the validity of SNAPPE-II score as a predictor of mortality and morbidity. Materials and Methods: A total of 248 neonates who met the inclusion criteria were included in the study and SNAPPE-II score was calculated. Receiver Operating Characteristic (ROC) curve was constructed to derive the best cut-off score and SPSS package (Statistical Package for the Social Sciences) was used for statistical analysis. Results: SNAPPE-II score was higher among expired neonates compared to survived ones. A mean score of 37 was associated with higher mortality. However, it didn’t accurately predict the length of stay. Conclusion: SNAPPE II score is a better predictor of mortality irrespective of gestational ages and it is not a good predictor of morbidity.
